object.DropDown= string
Read/Write at run time and design time.
{F4} is the default
Sets/returns the key or keys to open the drop-down object during data entry. A maximum of five keys can be set in the DropDown property. When setting multiple keys, use a comma (",") as a delimiter. There are keys that are used by Windows, such as [F10], and so on, which will not function as the user may expect if assigned to the control.
TDBDate.Key.DropDown = "{F4}"
In this example, calendar will pop up when [F4] is pressed.
If the Enabled property for the DropDown object is set to False, all keyboard interactions (keys assigned) and user-generated events will be ignored.
By default, the ALT+DOWN combination keys will drop down the calendar.
You can also drop down the calendar by calling the Drop method, which will cause the calendar to drop down when the control receives the focus. This will cause the DropOpen event to occur.
If the TDBText control's MultiLine property is set to True, all features for the drop down edit window will be disabled.
This property was named KeyPopup in the previous versions.
